Can you do the same with mid-drives too?

One of the reasons I drive a 30-year-old Range Rover is that I have a complete copy of all the service documentation for it, in an easily-downloadable 500MB zip file which also includes manuals for a bunch of other models. I need roughly the same number of specialised tools to maintain and repair it as I do to repair and maintain my (perfectly ordinary non-electric) bike, although all the individual components are far heavier and considerably more likely to get oil all down my trousers.

Permaculture starts with things you can repair.
